如何将转WDM化为KDM?就是那个DebugPrint for 2000转为for NT

就是《windows WDM设备驱动程序开发指南》中的debugPrint例子,没有与实际硬件交互，用于调试打印内核dbg信息，小弟想将其改造后在NT下使用
，我比较了一下，大部分函数，很类似，我
将wDM.h ->ntddk.h
并改动了很多编译没有通过的地方，
后来编译通过了，并且服务业可以启动(DriverEnrty顺利通过)，

但是CreateFile时候，说是设备未就绪，
跟踪驱程，发现根本就没有进入到DbpCreate,
请问大侠，这是什么问题？
将WDM->KDM除了去掉PNP外，还要注意什么？


谢谢！
改动后代码如下：
